Order value. Figure 3A is a schematic illustration of the gray scale distribution of display area 161 in accordance with an embodiment of the present invention. FIG. 3B is a schematic diagram of the gray scale distribution after the extension of FIG. 3A. Referring to FIG. 3B′, in the embodiment, the gray scale value of the display area 161 is used as an example, but not limited thereto, and the adjustment operations according to the gray scale distribution of the display areas 163 , 165 , and 16^ can be referred to the following. Description. In the figure, the statistical values of the grayscale values 0 to 255 are listed. As shown in the figure, the maximum grayscale value of the statistical value is not ,, so the present embodiment can use the grayscale value of 10〇 as the numerical value.
201208371 IU1UU44ITW 34525twf.doc/I 最大分佈灰階值。 接著,將灰階值0〜160延展為灰階值〇〜255,亦即將 灰階值0〜160同時乘上調整增益1.6 (約為255/160)。換 言之’每個縮放顯示資料SDD原本的灰階值會乘上調整增 益1.6 ’以使灰階分佈的範圍會等於灰階值〇〜255,其灰階 分佈如圖3B所示,亦即圖2中的資料調整信號DRS為依 據調整增益而產生,以使資料調整單元230延展圖3A所 不灰階分佈·。 由於原本有統計值的灰階值為〇〜16〇,因此在延展之 後會有部分灰階值沒有統計值。此時,由於延展之後,每 個縮放顯示資料SDD對應的亮度會提升,為了使顯示面板 160顯示原本縮放顯示資料SDD的亮度’因此可調整對應 的發光群組(即BG1)的亮度。舉例來說,若發光群組 BG1的發光亮度預設為1〇〇%,在延展之後則可調整為 62.5% (即1〇〇%/1.6)。藉此,可維持原本畫面的亮度, 並且可降低發光群組BG1的發光亮度,以降低發光群組的 電力消耗。 此外,由於畫面中較亮的部分較不易察覺亮度的變 化,亦即在高灰階值的部份中較不易察覺灰階值間的差 異。因此,如參照圖3A所示,在本實施例中,亦可設置 一臨界值TH來決定最大分值灰階值。依據上述,由於灰 階值151〜160的統計值小於臨界值,因此灰階值151〜160 可被忽略而不影響晝面整體的顯示,並且由於灰階值15〇 的統計值大於臨界值,因此灰階值150可被當作最大分佈 11201208371 IU1UU44ITW 34525twf.doc/I Maximum distribution grayscale value. Next, the grayscale values 0 to 160 are extended to grayscale values 〇 to 255, that is, the grayscale values 0 to 160 are multiplied by the adjustment gain of 1.6 (about 255/160). In other words, 'the original grayscale value of each scaled display data SDD will be multiplied by the adjustment gain of 1.6' so that the range of the grayscale distribution will be equal to the grayscale value 〇~255, and the grayscale distribution is as shown in Fig. 3B, that is, Fig. 2 The data adjustment signal DRS is generated based on the adjustment gain so that the data adjustment unit 230 extends the gray scale distribution of FIG. 3A. Since the grayscale value of the original statistical value is 〇~16〇, there will be no statistical value for some grayscale values after the extension. At this time, since the brightness corresponding to each of the zoom display materials SDD is increased after the extension, in order to cause the display panel 160 to display the brightness of the original zoom display material SDD, the brightness of the corresponding light-emitting group (i.e., BG1) can be adjusted. For example, if the illumination level of the illumination group BG1 is preset to 1〇〇%, it can be adjusted to 62.5% after extension (ie, 1〇〇%/1.6). Thereby, the brightness of the original picture can be maintained, and the light-emitting brightness of the light-emitting group BG1 can be lowered to reduce the power consumption of the light-emitting group. In addition, since the brighter portion of the picture is less noticeable in brightness variation, that is, the difference between the grayscale values is less noticeable in the portion of the high grayscale value. Therefore, as shown in Fig. 3A, in the present embodiment, a threshold value TH may be set to determine the maximum score gray scale value. According to the above, since the statistical values of the grayscale values 151 to 160 are smaller than the critical value, the grayscale values 151 to 160 can be ignored without affecting the overall display of the facet, and since the statistical value of the grayscale value 15〇 is larger than the critical value, Therefore the gray scale value 150 can be regarded as the maximum distribution 11

The extension of the gray scale distribution and the adjustment of the illumination group are similar to the above description, and therefore will not be repeated. Since the maximum distribution gray scale value is changed from 16 〇 to 15 〇, the adjustment gain value is changed from 1.6 to 1.7, so that the brightness of the light-emitting group can be adjusted down to 59%, thereby reducing the power consumption of the light-emitting group. FIG. 4 is a schematic structural view of the display panel 16A and the backlight modules 171 and 173 according to an embodiment of the invention. Referring to FIG. 4, in this embodiment, each of the light-emitting groups has four light-emitting diodes, that is, the light-emitting group BG1 has light-emitting diodes L11 to L14, and the light-emitting group BG2 has light-emitting diodes. In the bodies L21 to L24, the light-emitting group BG3 has light-emitting diodes L31 to L34, and the light-emitting group BG4 has light-emitting diodes L41 to L44. Each display area has nxm elements arranged in an array, that is, the display area 161 has a pixel All~Anm, the display area 163 has a picture B11~Bnm, the display area 165 has a picture cn~Cnm, and the display area 167 It has a halogen D11~Drnn, where 11 and m are a positive integer. When the pupil surface is displayed, the light-emitting diodes L11 to L14 provide the surface light source required for the pixels Al 1 to A nm, but cause optical interference to the halogens b丨丨吒唧, C1 and D11 to Dnm. Similarly, the light-emitting diodes L2 to L24 provide the surface light source required for the halogen B11 to Bnm, but cause optical interference to the pixels All~Anm, C11~Cnm, and D11~Dnm, and the others are deduced by analogy. According to the above, each lighting group will provide the required surface light source to the corresponding display area, but will also cause optical interference in other display areas. Therefore, the light-emitting groups BG1, BG2, BG3, and BG4 can be sequentially turned on to measure each of the halogens (such as A1 hAnm, B1丨~Bnm, α, and D11~Dnm) from the non-corresponding light group.
